Kind of toy plane with adjustable track

ABSTRACT

A toy plane with adjustable track of this practical new type consists of the airframe and wings made of light material such as physically cross-linked polystyrene foam. The characteristics are as follow: on the back-end extension surface of the airfoils, there is an empennage connecting with the back-end of the airfoils, and there are controls on the angle between the empennage and the airfoils. There is a flank vertical to the airfoil on the back-end of the upper surface of the airfoil, whose forepart is fastened at the airfoil. Also there are controls on the flank&#39;s swing on the upper surface of the airfoil. And there is a pothook at the forepart of the airframe. This practical new type is made by light material, which can realize the flight with the principle of spring. That is to say, put the pothook of the elastic and pull towards the back, after you loosen the elastic, the plane will fly away under the effect of elasticity. The track can be adjusted through altering the angle between the empennage and the back-end of the flank. The toy is extremely safe for playing, since the material is made by a light material with curved design, not easy broken material.

TECHNICAL DOMAIN

The practical new type is a kind of toy, especially a toy plane.

TECHNICAL BACKGROUND

At present, most toy planes on the market are just model planes used asornaments. Although some could be flying in the sky, they are usuallydriven by electricity. Thus, the structure is complicated, the price ishigh and it is difficult to make. Furthermore, their track can hardly beadjusted.

DESCRIPTION OF THE NEW TYPE

It is for a kind of toy plane that can fly in the sky and also canadjust the track.

And the goal is achieved by means of the following technological scheme:

A toy plane with adjustable track of this practical new type consists ofthe airframe and wings made of light material; on the back-end extensionsurface of the airfoils, there is an empennage connecting with theback-end of the airfoils, and there are controls on the angle betweenthe empennage and the airfoils. There is a flank vertical to the airfoilon the back-end of the upper surface of the airfoil, whose forepart isfastened at the airfoil. Also there are controls on the flank's swing onthe upper surface of the airfoil. And there is a pothook at the forepartof the airframe. This practical new type is made by light material,which can realize the flight with the principle of spring. That is tosay, put the pothook of the elastic and pull towards the back, after youloosen the elastic, the plane will fly away under the effect ofelasticity. The track can be adjusted through altering the angle betweenthe empennage and the back-end of the flank.

In order to make the operation more convenient, the above-mentionedcontrols include the screw and bracket which is installed on theairfoils. The screw supported by the bracket goes through the empennageand flank as screw thread. Once you turn the screw, the angle of theempennage and the range of the swing of the flanks can be adjusted. Whenturning the screw, the empennage and flank are easy to be damaged, sothe enforced plates are placed.

To make the operation easy, the handle is set at the back of the body;you can hold the handle when the plane is to be spring out of theslingshot.

The above-mentioned light material is foam.

And the following are the advantages of the plane: the orbit could bechanged; the structure are simple; easy to operate; easy to make; thecost is low.

ILLUSTRATIONS

To further describe the details of the practical new type plane, pleasesee the following illustrations:

FIG. 1: the front of plane;

FIG. 2: the left view of the plane;

FIG. 3: A-A cross section of FIG. 1;

FIG. 4: B-B cross section of FIG. 1;

OPERATION

From FIG. 1 to FIG. 4, we can see:

-   1: the head;-   2: the airframe;-   3: the wing;-   4: empennage;-   5: the flank;-   6: the angle adaptor and the pothook.

Among them item 1 to item 5 are made of foam, and item 6 are make ofplastic; item 4 on item 3 and item 3 are connected at a certain angle,item 5 are inserted to the wing by 5 a; by swinging 5 b, you couldchange the flank's angle. The angle adaptors are set between item 4 anditem 3, but also between item 5 and item 3. Item 6 is set at the back ofthe item 1. The back of the item 2 extends outside of item 4, so that wecan hold the toy plane in our hand and make it spring out of theslingshot.

The angle adaptor is made up with the bracket and the screw. And it isfastened at the back of item 3 by one part of the bracket (7). Anotherpart of the angle adaptor is made up with the bracket and the screw. Andit is fastened at the back of item 3 by one part of the bracket (7). Theother part is at the back of the back wing. Screw 8 is set at thebracket 7 and the back wing 4, it is connected between pole 8 and backwing 4. The angle adaptor between item 5 and item 3 are being “U” viabracket 9. The 2 sides of the shelf 9 a and 9 b are inserted from item3, the bottom part 9 c are stick to the back of the item 3, item 5 isbetween 9 a and 9 b; through item 5, each side of pole 10 is fastened tothe hole of 9 a and 9 b; pole 10 and item 5 are connected; force plate11 is set into the hole of item 4 and item 5.

When operating, put the pothook 6, which is at the back of head 1, tothe elastic of the slingshot, and pull the plane backward by holding theback of body 2, after you let go of your hand, the plane springs out bythe spring force. By swinging the screw of the angle adaptor, the angleof the empennage and the flank could be changed, at the same time thetrack of the plane could be changed.

1. This is the toy plane whose flying orbit can be changed and thefuselage and the wings are made of the light materials. The characteris: At the end of the extending surface of the wings there is afolding-empennage, which is connecting with the back of the wings:Between the empennage and the wings there is a package that is suing forthe regulation for the sticking-up-empennage and wing angles. The endingtip of the surface of wings has flanks that are at a right angle to thewings. The front of the flanks will be fixed up at the wings. Theregulation part exists at the surface of the franks for the swingingleftwards and rightwards. The descriptive fuselage has pothooks. 2.According to the first right claim, the characters of the toy planewhose flying orbit can be changed are: The descriptive regulation partincludes the screws and brackets, the descriptive brackets on the wingsare going through the wings and the flanks by the screws with thebrackets.
 3. According to the second right claim, the characters of thetoy plane whose flying orbit can be changed are: there are somefortified piece at the screws of the empennage and the flanks. 4.According to the first right claim, the characters of the toy plane withadjustable flying orbit are: At the back-end of the fuselage there aresome handgrips.
 5. According to the first right claim, the characters ofthe toy plane with adjustable flying orbit are: The above-mentionedlight materials are made of foam.
